The covers have button closure. Smoke free home. We used these covers on a freestanding expandable closet organizer with hanger rods in the middle (I've added a stock photo of a similar item for ease of explanation.) The rods had to go through the covers, so we modified the covers and cut small openings, and reinforced them so they slide easy. You can simply remove the reinforcement metal rings and patch the holes, or use as is. The modifications are pictured. Two holes each, one cover on the right, one on the left. An easy fix. Very little staining on the covers.
